The vapor pressure of water and the partial pressure of hydrogen contribute to the total pressure of 715 torr. What is the parti
Lostsunrise [7]

Answer:

0.91 atm is the partial pressure of just hydrogen gas.

Explanation:

Vapor pressure of water , p= 0.0313 atm

Partial pressure of hydrogen gas = p_{H_2}

Total pressure of the water vapors and hydrogen gas = P = 715 Torr

1 atm = 715 Torr

715 Torr=\frac{715}{760} atm=0.94 atm

According Dalton's law of partial pressure:

P=p+p_{H_2}

0.94 atm=0.0313 atm+p_{H_2}

p_{H_2}=0.94 atm - 0.0313 atm =0.9087 atm \approx 0.91 atm

0.91 atm is the partial pressure of just hydrogen gas.
